Preparation of raspberry-like ZIF-8/PS composite spheres via dispersion polymerization

Raspberry-like ZIF-8/PS composite spheres are prepared via dispersion polymerization of styrene with ZIF-8 and PVP as co-stabilizers. PVP is found to be crucial in determining morphology of the final product. It helps adherence of ZIF-8 nanoparticles to PS spheres. It is found that ZIF-8 nanoparticles thus prepared are partially embedded into PS sphere surfaces, resulting in a stable raspberry-like structure. Surface coverage of ZIF-8 can reach …
